APPARATUS FOR DRAWING WIRE.

SPECIFICATION forming part of Letters Patent No. 424,839, dated April 1,1890.

Application filed August 26, 1.889- Serial No. 321,960. (No model.)

To @ZZ whom it may concern,.-

Be it known that l, JOSEPH W. WHITE, of Cleveland, in the county ofCuyahoga and State of Ohio, have invented certain new and' usefulImprovements in Apparatus for Wire-Drawing; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it pertainstomake and use the same.

My invention relates to improvements in apparatus for wire-drawing; andit consists in certain features of construction and in combination ofparts, hereinafter described, and pointed out in the claims.

ln the accompanying drawings, Figure l is Fig. 2 is a plan.

'A represents a bench for supporting the apparatus, and ll a reel onwhich is placed a coil of wire that is to be drawn.

C, D, and lE are drums mounted, respectively on shafts C', D', and E',power being applied to each shaft, and the drums are usually rotated atthe same speed, although this is not material.

F and G are standards or housings for supporting each a series of dies,respectively f and g, the dies of each series being placed one above theother in the respective housings. Drums C andD are draft-drums, beingused solely for pullingthewire through the different dies. These drumshave each a series of circumferential grooves, respectively c and d,these grooves being usually something less than semieircular incross-section. These grooves may be quite' shallow, being intended onlyto keep the wire in place on the respect` ive drums opposite therespective dies. The finished wire is wound on drum E, this drum havingno grooves and the end of the wire being fastened thereto, this drumserving also as a draft-drum in pulling the wire through the last die,and more especially in giving tension to the wire, by means of whichtension the diderent coils of wire are succesL sively tightened on drumsC and D. The coil of wire having been placed on the reel, the free endof the wire is pointed, so that the end thereof may be passed throughthe different dies, 'lhe end of the Wire is first passed, for instance,through the lower die f and drawn by hand until there is enough drawnwire to Wrap once or twice around drum D, after which wrapping the wireis passed by hand through the lower die g, and from thence around drumC, and back through the second die f from the bottom, and again wrappedaround drumY D, and so on throughout the required number of dies, thewire leading from the upper die f directly onto drum E. Drum E, having,as aforesaid, the end of the wire fastened thereto, pulls the wirethrough the upper dief, and in so doing tightens the upper coil of wireon drum C, causing the latter to draw the wire through the upper die g,and this in turn tightens the upper coil on drum D, such retrogradeaction of tightening coils extending throughout the dies and coils ondrums O and D, and causing each drum to draw the wires. through thedifferent opposing dies. In placing the wire upon drums C and D, asaforesaid, it is only necessary to draw the wire by hand through therespective successive dies. The drums, being in motion, draw the wiresthrough the dies in which the wire had previously been inserted andwound from thence around the drums. For instance, the wire having beendrawn by hand through the first lower dief and passed from thence arounddrum D, by afterward tightening this coil by drawing on the Wire by handthis drum draws the wire through the iirst die uut-il there is enoughslack wire to pass through the lower die g and to wrap around the drumC, after which by again drawing on the end of the wire the two drums Oand D draw the wire through the first two dies, and so on. It will beunderstood that the drums C and D have little or no effect on the wiresolong as the coils areloose on these drums, and that the drums only pullthe wire as the coils are tightened by drawing on the advance end of thewire, and hence, although the wire is elongated in passing through therespective dies, the slipping of the drum in the diiferent coils ofWire, except as these coils are Vtightened by the draft of the coil nextin advance, causes the entire system to'operate automatically.
